Question 420

Acceptance testing must establish the following operational result: End-to-end run evidence proves the compute handoff. Which verification action most directly establishes that outcome?

  1. Check notebook output lineage and pipeline run completion.
  2. Re-run a pipeline from immutable raw input into curated output.
  3. Run a source connection test and inspect integration runtime health.
  4. Test dependency ordering, retry behavior and failed-run alerts.

Explanation

Correct Answer

A:

End-to-end run evidence proves the compute handoff.

Incorrect Answers

B:

This is a test for A data lake contains mixed structured and semi-structured datasets requiring repeatable transformations. The requirement here is instead demonstrated by check notebook output lineage and pipeline run completion.

C:

That verification addresses the different requirement: An enterprise requires secure connection to on-premises SQL data without exposing it publicly. It does not directly establish end-to-end run evidence proves the compute handoff.

D:

That verification addresses the different requirement: Daily batch files require mapping, copying, transformation and scheduled dependencies across systems. It does not directly establish end-to-end run evidence proves the compute handoff.

Question 421

An enterprise requires secure connection to on-premises SQL data without exposing it publicly. Which Azure architecture choice best meets this requirement?

  1. Use a supported self-hosted integration runtime for hybrid Data Factory connectivity.
  2. Open the on-premises database broadly to anonymous Internet access.
  3. Expect an ordinary Copy activity to implement every complex Spark transformation.
  4. Schedule dozens of unaudited VM cron jobs with hardcoded credentials.

Explanation

Correct Answer

A:

The integration runtime bridges eligible private sources to orchestrated data movement.

Incorrect Answers

B:

Public anonymous exposure violates the private connectivity requirement. This proposal contradicts the stated architecture constraint.

C:

Data copy does not replace the transformation engine's logic. In the present requirement, an enterprise requires secure connection to on-premises SQL data without exposing it publicly. The needed design instead works because the integration runtime bridges eligible private sources to orchestrated data movement.

D:

Distributed scripts make lineage, governance and failure handling fragile. In the present requirement, an enterprise requires secure connection to on-premises SQL data without exposing it publicly. The needed design instead works because the integration runtime bridges eligible private sources to orchestrated data movement.

Question 422

An architecture proposal for data factory orchestration relies on the following approach: Open the on-premises database broadly to anonymous Internet access. Which specific failure or mismatch should the design reviewer identify?

  1. Data copy does not replace the transformation engine's logic.
  2. A small transactional SQL tier is not a general Spark analytics engine.
  3. Public anonymous exposure violates the private connectivity requirement.
  4. Distributed scripts make lineage, governance and failure handling fragile.

Explanation

Correct Answer

C:

Open the on-premises database broadly to anonymous Internet access. Public anonymous exposure violates the private connectivity requirement.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Expect an ordinary Copy activity to implement every complex Spark transformation.' not to the recommendation under review. Here, Public anonymous exposure violates the private connectivity requirement.

B:

This concern applies to Use one Azure SQL Basic database to execute unlimited distributed Spark jobs. in another design data integration design. The current proposal specifically fails because public anonymous exposure violates the private connectivity requirement.

D:

That assessment refers to the separate proposal 'Schedule dozens of unaudited VM cron jobs with hardcoded credentials.' not to the recommendation under review. Here, Public anonymous exposure violates the private connectivity requirement.

Question 423

Acceptance testing must establish the following operational result: Connectivity proof confirms the integration remains private and functional. Which verification action most directly establishes that outcome?

  1. Run a source connection test and inspect integration runtime health.
  2. Test dependency ordering, retry behavior and failed-run alerts.
  3. Check notebook output lineage and pipeline run completion.
  4. Run a representative Spark batch and SQL analytics query.

Explanation

Correct Answer

A:

Connectivity proof confirms the integration remains private and functional.

Incorrect Answers

B:

That verification addresses the different requirement: Daily batch files require mapping, copying, transformation and scheduled dependencies across systems. It does not directly establish connectivity proof confirms the integration remains private and functional.

C:

That verification addresses the different requirement: A transformation must run as Spark notebooks after data is copied from operational stores. It does not directly establish connectivity proof confirms the integration remains private and functional.

D:

This is a test for A company stores large data lake files and needs distributed SQL and Spark analytics. The requirement here is instead demonstrated by run a source connection test and inspect integration runtime health.

Question 424

Millions of IoT sensor events per hour must be ingested with parallel consumers. Which Azure architecture choice best meets this requirement?

  1. Delete an event immediately after the first consumer acknowledges it.
  2. Place an Event Hubs namespace root key in every analytics container image.
  3. Use Azure Event Hubs with suitable partitions and consumer groups.
  4. Use one Service Bus session queue as if it were a massive event retention log.

Explanation

Correct Answer

C:

Event Hubs supports high-throughput append-only event streaming.

Incorrect Answers

A:

Single-consumer deletion removes the stream replay pattern. In the present requirement, millions of IoT sensor events per hour must be ingested with parallel consumers. The needed design instead works because event Hubs supports high-throughput append-only event streaming.

B:

Shared root keys expand leakage and administration risk. In the present requirement, millions of IoT sensor events per hour must be ingested with parallel consumers. The needed design instead works because event Hubs supports high-throughput append-only event streaming.

D:

Message queues have different throughput and replay characteristics from event streams. This proposal contradicts the stated architecture constraint.

Question 425

An architecture proposal for event hubs high-volume stream ingestion relies on the following approach: Use one Service Bus session queue as if it were a massive event retention log. Which specific failure or mismatch should the design reviewer identify?

  1. Shared root keys expand leakage and administration risk.
  2. Message queues have different throughput and replay characteristics from event streams.
  3. Uncontrolled raw-layer modification destroys reproducibility and lineage.
  4. Single-consumer deletion removes the stream replay pattern.

Explanation

Correct Answer

B:

Use one Service Bus session queue as if it were a massive event retention log. Message queues have different throughput and replay characteristics from event streams.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Place an Event Hubs namespace root key in every analytics container image.' not to the recommendation under review. Here, Message queues have different throughput and replay characteristics from event streams.

C:

This concern applies to Let every reporting user overwrite the raw landing files. in another design data integration design. The current proposal specifically fails because message queues have different throughput and replay characteristics from event streams.

D:

That assessment refers to the separate proposal 'Delete an event immediately after the first consumer acknowledges it.' not to the recommendation under review. Here, Message queues have different throughput and replay characteristics from event streams.

Question 426

Acceptance testing must establish the following operational result: Consumers reading at separate offsets prove stream fan-out. Which verification action most directly establishes that outcome?
